**Question #30 2.4**: A square field has an area of 1000m². Laura wants to walk from one corner of the field to the opposite corner. If she walks at 1.5 m/s, how much time can she save by walking diagonally instead of walking along two adjacent sides? Express your answer to the nearest tenth of a second.

Step 1) Find the square root of the area or find the side length of the square

Step 2) Find the distance of the 2 adjacent sides

Step 3) Figure out how long it takes to walk the two adjacent sides

Step 4) Find out how long it takes to walk diagonally

**Solution:**

Subtract the time it takes to walk diagonally from the time it takes to walk the 2 sides.

42.25 - 29.85 =

**12.4**seconds.Laura saves 12.4 seconds by walking diagonally instead of walking the two adjacent sides.
